How To Send An Sms With Custom Sender Id With Amazon Sns And Python And Boto3

The documentation suggests to use message attributes for that but I can't seem to figure out what attribute name to use. This works so far: sns = boto3.client('sns', region_name='e

Solution 1:

The sender id must be 1-11 alpha-numeric characters, no spaces; for example:

• THISISME - ✅
• TestForSO - ✅
• StackOverflow - 🛑 (too long. max 11 chars)
• Some one - 🛑 (no spaces)

As others mentioned, the sender id customization depends on the country / cellular provider so make sure to test it.

Example snippet

import boto3

access_key = '....'
secret = '....'
region = "us-east-1"number = '+972...<your number>'

sender_id = 'TestForSO'
sms_message = 'Your code: 123456'

sns = boto3.client('sns', aws_access_key_id=access_key, aws_secret_access_key=secret, region_name=region)
sns.publish(PhoneNumber=number, Message=sms_message, MessageAttributes={'AWS.SNS.SMS.SenderID': {'DataType': 'String', 'StringValue': sender_id}, 'AWS.SNS.SMS.SMSType': {'DataType': 'String', 'StringValue': 'Promotional'}})

Solution 2:

Check if your destination country supports sender IDs

http://docs.aws.amazon.com/sns/latest/dg/sms_supported-countries.html

Solution 3:

As noted by Adam Owczarczyk, some countries don't allow you to transmit a sender ID in a text message. The API will take your number and replace it with a string in this case to allow your message to get delivered. Attempting to work around it usually just gets the number blacklisted. You can test this by entering a short descriptive string for your tester ID, and seeing if that gets through.
